When Awesome wants to go to Africa with Ellie, and Morgan and Casey want to follow Chuck to Rome as members of his team, the three of them team up to help Chuck with Sarah back. They steal Lester's stalking van and take Chuck on a mission to crash Shaw and Sarah's date. Morgan draws Shaw outside via a phone call to distract him, and they end up getting cornered by ring operatives that want to take Shaw in. Devon ends up saving Shaw by tackling him inside the restaurant. Chuck, meanwhile, inside, pours his heart out to Sarah, but doesn't quite win her over.
At home, Ellie convinces Chuck he didn't go far enough. Chuck visits Sarah, who tells him Shaw has turned himself in to the Ring in order to track his location and order an air strike. Chuck, knowing how much Shaw means to Sarah, goes to rescue Shaw. Shaw's tracking device is removed, but luckily Jeff and Lester, desperare to prove their worth as stalkers, have been tailing Sarah's "new stallion." Far underground, Shaw is shown video footage by the Ring of Sarah killing his wife. After an intense mission, Chuck makes it out with a passed out Shaw.
Back at Castle, Chuck tells Sarah he loves her, kisses her, and tells her they should give up the spy life and meet at the train station tomorrow. But it's really Casey, who shows up at Sarah's apartment and tells her Chuck never killed the mole, he did, that won her over. Just as she's packed and prepared to meet him, Shaw, with his wedding ring back on, picks up Sarah for "an emergency mission."
